First shear stress (Pa)

Last shear stress (Pa)

First and last shear stress to apply during the determination of the deformability curve. By taking "First" higher that "Last", the curve will be completed in reverse order.

Initial image stabilisation time (ms)

Following camera adjustment at a high shear stress, the measurement starts with the "first measurement-shear stress", described above. The cells in the suspension need time to adjust to each new shear stress, especially when the shear stress for camera adjustment is high compared to the first measurement-shear stress. This parameter defines the initial cell stabilisation time following camera adjustment. If the standard deviation of the elongation measurement at the first measurement-shear stress is still quite high, the initial stabilisation time may need to be increased.

Intermediate image stabilisation time (ms)

Like the stabilisation time mentioned in the former parameter description, the cells in the suspension need time to adjust to each new shear stress. This parameter defines the time for stabilisation of the suspension between subsequent elongation measurements.

Measuring points on curve

Determines the number of shear stresses that are used to build up the deformability curve.

Valid determinations per shear stress

Prescribes the number of subsequent EI determinations (each from a newly acquired diffraction image) to find the average EI (and SD) per shear stress.
